In this blog post, Debora Catavello shares some preliminary findings from an exploratory study into EAP materials that she conducted in 2023. In her study, Debora starts with the premise that teaching materials are the ‘instantiation of principles drawn from the broad fields of second language acquisition theory and language teaching theory‘ (Timmis, 2002, p. 217). She then examines the extent to which a set of her own materials aligns with the principle of authenticity, and explores ways to resolve the so-called ‘EAP genre paradox’.
